VAPORIZER.

SPECIFICATION forming part of Letters Patent No. 794,387, dated July 11, 1905.

Application filed August 10, 1903. Serial No. 168,975.

To all whom it may concern.-

sages, of a medicated vapor for healing and curative purposes. Numerous devices of this general character which operate by a process of inhalation on the part of the patient have been devised and used, an instance of which is shown in Letters Patent No. 349,085, granted September 14, 1886, to James F. Chesebro.

The present improvement has for its principal object to effect a superior and more extended use of such adevice through an attachment in the nature of an air-forcing pipe or tube having a mouthpiece which dispenses with the necessity of the inhaling operation on the part of the patient and enables the medicated vapor to be positively forced into contact with the diseased parts.

To this end the invention consists in a vaporizer for the purpose stated constructed and operated substantially in the manner hereinafter described, and more particularly pointed out in the claim.

A device embodying the invention in an improved form is illustrated in the accompanying drawings, wherein Figure 1 is a central vertical section through the main receptacle and its contents, and Fig. 2 is a detail perspective view of the detachable and removable blowpipe constituting the chief novel feature of the present invention.

In the drawings, 5 designates the main receptacle, which may be formed of any suitable material and in any convenient size and shape, the receptacle being preferably of glass in order to afiord at all times a view of the contents and to enable the user to readily ascertain the amount of medicated liquid therein and to know when recharging is required.

The upper end of the receptacle may be closed by a suitable stopper 6, which is apertured for the insertion therethrough of a vapor-discharge tube 7 and for the hollow stem 8 of a bulb 9, adapted for the reception of some usual acid for a medicated vapor, such as hydrochloric acid 10, which may be poured therein through the open upper end of the stem 8. A tube 11 branches laterally from the hollow stem 8 at a point between the bulb and the stopper and extends nearly to the lower end of the receptacle through a bodyof medicinal liquid 12, contained in the receptacle 5, which may contain the usual alkali, such as ammonia.

The device as thus far described corresponds substantially with the vaporizing-inhaler disclosed in the Letters Patent to Chesebro hereinabove referred to, such device having heretofore been capable of use solely as an inhaler by utilizing the tube 7 as a mouthpiece through which air drawn from the outside through the hollow stem 8, over the liquid 10, through the branch tube 11, and up through the liquid 12 and impregnated by the vapors of the medicinal liquids has been inhaled by the patient. Experience has demonstrated that numerous situations arise wherein the application of the medicated vapor by the process of inhalation is impractical or impossible, such as in the cases of children too young to use the vaporizer through the regular plan of inhalation or of elderly people too sick or otherwise incapable of using the vaporizer in such a way. In order to enlarge the scope of the device and enable it to be successfully used in such cases, I have provided in lieu of the funnel G shown in said patent an attachment or appur tenance in the nature of an air-supply pipe adapted to conduct a currentof air blown therethrough, whereby a physician, nurse,orattendant may readily force the medicated vapor through the discharge-pipe 7 not only to such parts as are ordinarily reached by the inhalation process, but also to parts that would be incapable of treatment through the latter. This air-pressure-supply pipe in the preferred form herein shown consists of a bent glass tube comprising a straight vertical lower portion 13, adapted for insertion through the stem 8 into the bulb 9, and an outer inclined portion 14, terminating in a flattened and enlarged mouthpiece 15. This supply pipe or tube is preferably made of glass throughout and is provided with an integral collar 16 at "or near the upper end of its :lower ve rtical member, which collar sits on the upper end of the stem 8.

In practice when the device is to be charged the stopper 6 and the parts carried thereby are first removed and the medicinalliquid 12 introduced to the receptacle 5 to about the height illustrated. The stopper and the parts carried thereby being then replaced, the airpressure supply pipe is Withdrawn and the acid lO-introd'uced to thebulb 9"throu'gh the open upper'endof the hollow stem 8. The 'air-pressure supply pipe being then inserted in the position shown-in Fig. '1, the device is ready ="for 'use. The attendant directs theenlarged bulbous end-of the discharge-tube 7 agai'nst the "part or parts to be trea'ted-and applying the lipsto the mouthpiece 15 blows th'erethrough, thus forcing-a current-of :air

through and in con-tact with theacid'andalkaline liquids carried by the receptacle,

' whence the'air-"current, heavily charged with possesses several advantages, among which "maybe mentioned the follo'wmg: Being loosely pivoted in'the'hollow stem 8,the mouthpiece is capable of beingturned to anygiven angle relatively to thedischarge-tube 7. 'Be- :i'ng removable by-simply lifting itout of the hollow stem '8, it does not interfere withthe charging of the'bulb 9 and at-thesame time may itself be readily cleansed, and having'the making it possible to treat patients who are incapable of using the device itself as an in haler-and also rendering possible the treatment of parts incapable of being reached by the inhaling method.

The efliciency of the device as a disinfectmg, fumigating and steri'llzing apparatus for s1ck-roomsis=also"enhanced by reason of the greatly-increased "volume of the medicated vaporwhich may be; discharged therefrom.

I claim I The combination witha receptacl'e ad'apted to contain a body'of medicated liquid-and "a stopper therefor, 'of' a :bulb suspended-within said receptacle "by a hollow stem passed through "the stopper-thereof and adapted to contain a body of medicinal -aoid,:a :branc'h tube leading from said ihollow-stem into the liquid in said receptacle, *a avapor-discharge tube passed through said stopper, :andfia removable air-pressure=supply-pipeicomprising a vertical portion *interiorl-y"telescoping"said hollowstem-and entering said bu-lb, 'a=collar on said-vertical portion'adapted toiseat'on: the

upper end 'of said hollow stem, an outer in- 'clined branch, and a flattened and-widened mouthpiece at theend of said branch, all of said par'ts being madeintegral, substantially 'asand for the purposesdescribed.
